BICM-ID scheme for clipped DCO-OFDM in visible light communications.
Visible light communication (VLC) is recommended for indoor transmissions in 5G network, whereby DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) is adopted to eliminate the inter-symbol interference (ISI) but suffers from considerable performance loss induced by clipping distortion. In this paper, bit-interleaved coded modulation with iterative demapping and decoding (BI...
متن کاملImproved TKM-TR methods for PAPR reduction of DCO-OFDM visible light communications.
The dc-biased optical orthogonal frequency division multiplexing (DCO-OFDM) system is experimentally demonstrated as an appealing candidate in future visible light communication (VLC) system. However, the intrinsic high PAPR drawback that the DCO-OFDM system suffers from still needs to be addressed and few effective approach has been found so far. To deal with this problem, in this paper, the t...
متن کاملA Review: Visible Light Communication using MU-MIMO-OFDM
Visible Light Communication (VLC) is an approach which uses LEDs (Light Emitting Diodes) for lightning as well as for providing an opening for economical higher data transfer rate setup for wireless communication, which can be used as an alternative for effective and efficient communication that can merge with the demand for higher transfer rate wireless communication. In this paper, we take an...
متن کاملAn adaptive scaling and biasing scheme for OFDM-based visible light communication systems.
Orthogonal frequency-division multiplexing (OFDM) has been widely used in visible light communication systems to achieve high-rate data transmission. Due to the nonlinear transfer characteristics of light emitting diodes (LEDs) and owing the high peak-to-average-power ratio of OFDM signals, the transmitted signal has to be scaled and biased before modulating the LEDs. In this contribution, an a...
متن کاملCoded Modulation with APSK for OFDM-Based Visible Light Communications
Coded modulation with APSK is proposed for OFDM-based VLC systems. Simulation results show that the proposed scheme achieves better performance than conventional QAM counterpart in both DCO-OFDM and ACO-OFDM systems, while similar complexity is maintained. OCIS codes: (060.2605) Free-space optical communication; (060.4080) Modulation.
